Title (EN) VACUUM REGULATOR WITH ANTIBINDING VALVE STEM CONNECTOR ASSEMBLY AND METHOD
(FR) REGULATEUR A VIDE POSSEDANT UN ENSEMBLE ANTI-AGREGATION CONNECTEUR DE LA TIGE DE SOUPAPE, ET PROCEDE
Abstract:
(EN) A medical vacuum regulator (10) with a vacuum regulation chamber (20, 34) connected with a supply of unregulated vacuum (26) through a regulation control valve seat opening (24A) controlled by means of a valve head (28, 28A) at one end of a valve stem (30) extending through a valve stem guide (32) and coupled at its opposite end to a movable wall (36, 38) of the regulation chamber (20, 34) is provided with an antibinding valve stem connector assembly (12) comprising a ball and socket connector (46, 48) respectively coupled to the valve stem (30) and the movable wall (36, 38) to enable relative movement between the valve stem guide (32) and valve stem (30).
(FR) Régulateur à vide (10) à usage médical comportant une chambre (20, 34) de régulation du vide reliée à une source de vide non régulé (26) par l'intermédiaire d'un orifice de siège de soupape régulateur (24A) commandé au moyen d'une tête de soupape (28, 28A) située à une extrémité d'une tige de soupape (30) qui s'étend à travers un guide de tige de soupape (32) et qui est couplée à son autre extrémité à une paroi amovible (36, 38) de la chambre de régulation (20, 34). Ledit régulateur (10) est doté d'un ensemble anti-agrégation connecteur de la tige de soupape comportant un connecteur à rotule et logement de rotule (46, 48) couplés respectivement à la tige de soupape (30) et à la paroi amovible (36, 38) afin de permettre un déplacement relatif entre ledit guide (32) et ladite tige (30).
